remember this is a 10 not an 8/9.
My black hit 36-37psi by 4200rpms on DB's dyno last time on my 2.0L.
With an extra 10% displacement it should be another 400rpms or so lower on the EF4 I would think.
The EF4 is a bit bigger so it could be more like 4200-4400rpms but I wouldn't think over 4500rpms on the setup, we will see. I am also not boosting high 30's this time, so that is another factor.
